T 0 all whom it may concern:

Be it \known that we, WARREN C. EvANs and EUGENE H. TAYLOR, citizens of, the United States, residingat Exeter, in the county of Rockingham, State of New Hampshire, and at Lynn, in the-county of Essex and State of Massachusetts, (whose osto'llice addresses'are 76 Front street,.sai z EX- eter, and 747 Washington street, said Lynn, res ectively,) have invented a certain new amiuseiul, Improvement in Machines for F inishing the Heels of Boots and Shoes, of which the following is a specification, reference being had therein to the accompanying drawings. 1 r

I The invention consists invarious features of improvement which we have conveniently illustrated in the accompanying drawings, and whichwe Wlll now-proceed to-describe with reference to the said drawings. 1

In our improvedmachinea boot or shoe requiring to have the heel thereof finished applied to a jack, and while on the latter 1S brought into working relations with a number of finishing tools in succession, so that while the boot or shoe is in the machine its heel is automatically subjected to the re quired variety of finishing operations in the desired succession. We employ a series of finishing tools, and also a Workcarrier fur- .nished with a number of jacks arranged. to

receive and support a number of boots or shoes at a time while the heels thereof are simultaneously being acted upon by the finishing tools, the said work-carrier having combined therewith power-actuated shifting devices under the control of the operator,

whereby, at the will of the operator, theshaft-1', Figs. 1,2, 3, 4 and 7, in connection with which will beemployed in practice suitable means of transmitting driving power thereto and of shipping the said power on and off. Figs. land 2 show fast and loose band-pulleys 2, 3, of usual character for the purpose of receiving a driving band through which the driving'power is transmitted.

In Fig. 1 of the drawings, for the sake of clearne'ss, only one shoe 4 is shown, it being represented as supported in position to place its heeLunder the action of one of the tools of the machine. The workcarrier 5 is 'fur nished with a plurality of work-supports or jacks 6, 6. It is mounted upon a shaft 7', the latter having suitable bearings at 8 9 in con nec'tion with the machine frame, in which bearings said shaft is adapted 'to rotate and also to slide longitudinally. The work-sup-.

ports-or jacks are arranged. in a circular series u on the work-carrier. The number thereo is greater than the number of'toolshafts in the series of the latter, in order that one or more of the said work-supports or jacks shall occupy an intermediate position relative to the tools which will permit a boot or shoe which has been subjected to the required operations in turn to be removed from its work-support or jack and another applied to the latter. The machine shown has been .especially contrived with the object in view of enabling tools upon six tool-shaftslto be employed, and the work-carrier is provided with eight work-su ports or jacks. The machine, therefore, has six working points, which are two less in number than the worksupports or jacks.

In different machines the number of toolshafts-providedmay and will be variedin practice to meet the views and needs of the users of the machines, and hence while we have shown six tool-shafts and awork-carrier having eight work-supports or jacks we would have it understood that these particular numbers are not essential to the inven tion and may be varied from as found advisable to meet the requirements of practice. The work-carrier is shown constructed with two radiating series of arms. One arm of each of the said series cooperates with the corresponding arm of the other series in the support of a boot or shoe, and hence such a pair of arms with their appurtenances constitute a work-support or jack.

The construction of the work-supports or jacks may vary in practice to suit the needs in useor the views of thebuilders and users of our machine. We have shown herein work-supports or jacks embodying the features of invention which are claimed in our divisional a plication for U. S. Letters Pat cut for jacr for boot and shoe machinery filed March 29, 1905, Serial No. 252,617.

The arms 10 10 of one set of arms,'see Figs. 1, 2, 9 and 10, have screw-threaded holes formed through their outer extremities 11 11 and receive therein hand-screws 12, 12, each carrying at its inner end a form or last at 19, Figs. 9, 1 3 and 14. The arms 13, 13, of the other series, see Figs. 1, 2, 11. and 12 have pivoted thereto, as at 14, 14, clamping arms 15, 15, to the outer extremities of which in turn plates or blocks 16, 16, are swiveled or hinged, the said plates or blocks being intended to bearagainst the exposed faces of the heels of the boots or shoes that are mounted upon the lasts or forms which are carried by the hand-screws 12,112, of the other series of arms. The inner extremity of each hand-screw 12 has the corresponding last or form 19 removably connected therewith in suitable manner to prevent accidental "disengagement of the last or form from thehand-screw.

In Figs. 13 and 14, Sheet 10, the end of the hand-screw is enteredinto a socket 18 in the last or form 19. The said end is formed with a circumferential groove 20, Fig. 9, Sheet 9, and the last or form has a transverse slot 21, Fig; 9 and Figs. 13 and 14, Sheet 10, within which is fitted a latching lever 22, one extremity of which is acted upon by a spring 223' conveniently contained Within a cavity 1 in the'last or form, while'the other extremity thereof enters the circumferential groove 20 of the hand-screw. For retaining the last or form in a predetermined, osition upon the Work-carrier, usually radia while ermitting the same td be adjusted transverse y with relation to the tools, a pin 23, Fi 9, Sheet 9, and Fig. 13, Sheet 10, 1s attacher to each arm 10, the said pin extending parallel with the hand-screw and bein 24 that is form .d wit in the body of the last or form paralle with the socket for the handscrew. The said from. turning relatively to the work-carrier,

received within a hole but the last .or form is left free to be adjusted as desired in thedirection of the length of the hand-screw by means of the hand-screw. v I

The pivoted clamping arms 15, 15, Figs. 1 and 2, and Figs. 11 and 12, Sheet 9, of the other portion of the work-carrier are fur-- nished with worm-gear segments 26, 26, that are engaged by worms 27, 27, the said worms being mounted to turn in hearings in the fixed arms, and being provided with hand-wheels 28, 28, for convenience of manipulation. By means of these worms and their hand-wheels the pivoted'clamping arms 15, 15, may be 15 gperatedto cause their swiveled platesor ocks 16, 16, to bear against the faces of the top-lifts of the'heels which are op osite the same, or. to withdrawsaid swivelef plates or blocks from contact with the said top-lifts. The use of the worms and worm-wheels for adjusting the ivoted arms and their clamping lates or b ocks is preferable to the use of pew and ratchet devices for the same purpose. ,Pawls are liable to becomedisengaged 5 from their ratchets by the jar of the machine,

and they do not permit a sufficiently accurate adjustment of the parts to enable the heel-seat of a shoe to be adjusted with precision relativeto the tool. The worms and worm-wheels, on the other hand, hold the pivoted arms securely locked in the position which isgiven tothe latter. They are not subject to, such rapid wearas in the case of the ratchets, and consequently are less liable 5 to get out of order. a They permit, moreover,

a delicate and exact positioning of the heelseat of aboot or shoe relative to the cutter [and other tools which are intended to act upon the heel. 40 It is important to effect adjustment 'to a nicety of the heel-seat of a boot or shoe-which has been applied to a work-carrier or jack relative to the working tools, so that possibility of injury to the up er of a shoe by any of the tools shall be prec uded, \Vhlln the heel itself shall be perfectly and completely operated u on from the heel-seat to the bottom or outer ace of the top-lift.

The thickness and compressibility of the 5' uppers ofboots and shoes, of the inner soles thereof, and of the counter-stiffeners, vary quite considerably in practice, and inasmuch as the combined thickness, after compression between the last or form and the opposing 53-plate or block 16, of upper, inner sole, and counterstifiener flanges, intervening between the bottom of the last or form and the heelseat of a boot'or shoe, determines the. distance of the said heel-seat from the said hot- ;0 tom of the last or form, it is evident that as the said combinedthickness varies the said distance will also vary. Consequently, in the machine the position of the heel-seat of a boot'or shoe, mounted o'none of the lasts 5 or forms, relative to a tool to which the boot f or shoe is presented for action, would vary in dlflerent boots or shoes according as such combined thickness varies, 1f ad ustment a were not made 1n order to compensate therefor. This would result in some cases, if the said combined thickness should be Sulliciently great, in bringing the upper of the bootor shoe adjacent the heel-seat within some cases would not be presented within the rangeof action of the tool, and conse' quently theheel would not be completely finished; in others, injury to the heel would result from the action of a tool thereon at one side of the heel-seat. The variations which have just been referred to in the case of successive boots or shoes may be compensated for by the operator, if desired, by making adjustment of the hand-screws 1 2, 12. In this connection, however, we have aimed to render it possible to make one adjustment of the hand-screws 12, 12, before beginning work upon a givenline of shoes, and thereafter leave them undisturbed in their adjhstment, and to effect the required positioning'of the boots or shoes relative to the respective tools in jacking theboots or shoes by moving the clamping arms 15, 15, through the agency of the worms 27, 27, and worm-wheels 26, 26.

This has the advantages of rendering it unnecessary to use both hands in effecting the required adjustments during jacking, and expedites the performance of the jacking operatibns. is made yielding in a direction transverse with reference to the finishing tool. The capacity for yielding may be secured in a variety of ways. l 1

In the drawings the bottom of each last or form has applied thereto a yielding bearing To this end, each last or form portion intended to make contact with the surface of the inner sole of a boot or shoe thatv is ap lied to the last or form. \s the clamping b lock or late on the pivoted arm of the jack is caused by the adjustment of the said arm to pressagainst the exposedface of the top-lift of the heel of the boot or shoe, by the turning of the corresponding. worm by the operator, the said yielding bearing gives way under the pressure;- In this way the boot or shoe may be forced transversely until the heel-seat thereof'is seen to be in proper position relatively to thetools'. Herein, thesaid yielding bearing is constituted by a bent plate or strip of sprin 14;.Sheets 9 ant 10) which issecured at one end to the bottom of the last at or hear the toe-end of the latter, the other end being free and being sprung away from the bottom of the last to the required distance to provide Forthe desired amount of adjustment.

For the purpose of holding the boot'or shoe material 29 (Figs. 9, 13 and' which is mounted on the last or form firmly against turning uponthe latter while being acted upon by the tools, the last or form is furnished with spurs or points projecting from the bottom. thereof for engagement with the inner soie the boot or shoe. In the present instance the said spurs or points are arranged in position to pass through holes 31 that are made for the purpose'in the springstrip or plate that is attached to the bottom of the last or form as aforesaid. In the normal outsprung position of the said strip or plate, the latter stands beyond the ems of said spurs or points and covers or-shiclds the latter, so as to enable a boot or shoe to be slipped onto the lastor form. without engagement of the spurs or Points with the material of the boot or shoe, as, for instance, with the surface of the inner sole, which would result .in injurythereto. When the pivoted arm and its block or plate are adjusted by the 0 erator to clamp the boot or shoe firmly to t e, lastor form, the spurs or points protrude through the holes in the spring-strip or plate as the latter iscompressed, and enter into the inner sole. When the pressure of the said block or plate against the face of the heel isrelieved, the strip or plate springs away from the bottom of the ast or form again, once morecovering or shielding the spurs or points, so that the lat ter shall be prevented from interfering with .work to be performed.

the'removal of the boot or shoe, and from. occaslonmg mplry to the latter.

The various finishing tools which are employed in the machine are arranged in proper position adj acentthe path which is taken by the heel of a boot or shoe that is supported upon and being carried around by the worle carrier. The number and-character of the said tools will be varied in practice in accordance with the character. and needs of the The said tools are arranged in the order in which they are requiredto come into service in connection with a heel. l The work-carrier is given a step-by-step or intermittent rotativc movement, each advance thereof being suflicient to carry a shoefrom one tool to the next.

The successive advances of the work-carrier present the said boot or shoe. to each of the tools in turn. After a boot or shoe has had 7 the heel thereof subjected to the required number of operations, it is removed by the operator from. its jack during the dwcll'of tho work-carrier, and afresh shoerequiring to have its heel operated upon is applied to the said jack. In the illustrated machim-r the application and removal are effected by one operative at the front of the machine, but it will be obvious that in some cases the applicati'on may be cll'cctcd at one side of the machine and the removal at the other, and when this is done two operatives will be required, one standing at each side of the machine.

l/Ve have shown provisions for the employment of five rotating tool-shafts carrying tools for working on the periphery of the heels to be finished, and a reciprocatory breasting-cutter. The number of tools, and the precise character of the various tools, are not essential to the invention. In some cases, less than the full number of tools provided for may actually be employed, the others being omitted or removed, The tools of the present machine, might comprise, for instance, a trimming-cutter, a scouring tool,

a blacking tool, a burnishing tool, a heading tool, and the breastmg cutter, these being disposed in the order in which they havc just been named.

-The five rotary tool shafts are shown. at During the momcn- 34, 35 and 36. tary dwell of the work-chrricr, with. the respective work-supports or jacks thcrcof adjaccnt the respective tools, holding the shoes on said jacks in position to be acted upon by the said tools, each rotary tool -shalt is caused to travel around the circuit. of the heel upon which its tool is acting. For the purpose of causing the said tool-shafts and tools to travel or swing around the heels in the manner just referred to, leach tool-shaft is applied to a swinging or rocking tool-carrier; thus, the bearings 37, 38 for each rotary tool shaft are applied to a pair of arms 25$); 40 carried by opposite ends of a rock-shaft ll --which is furnished with suitable bearings upon the framework of the machine. Each rock-shaft has aliixed thereto a spur-pinion 42, Figs. 1, 2 5 and 6, which is in mesh with a toothed surface which herein is constituted by acurved rack in the form of a SLC-liOP-Q'P-ill 43, the latterbeingmounted on the shaft 431, which last is mountedin suitable bearings which are provided on the machine framing.

This sector-gear has-fast therewith a spurpinion 44, Fig. 5, and with the latter engages a toothed rack 45 on abar46 carrying a stud or roll 47 working in the groove 48, Fig. 5, of

a cam 49 fixed on a rotating shaft 50'mounted in hearings in the lower part of the ma chine. As the said shaft 50 and its cam a9 are rotated, the endwise movement of the rack-bar 46 which is communicated to the latter by the cam acts to occasion an oscillating movement of the sectorgear and causes the rocking-carriers of the tool-shafts to rock or swing first in one direction and then in the reverse direction The rack-bar is guided in its reciprocatory movements by means of pins or rolls -51, 51 the bearing 3h at the opposite end of the tool-shaft rocks or swivels upon the said trunnions or pivots.

For the purpose of adapting the mechanism, after working in connection with heels I of a given size, to operate in connection with heels ol'.a diilercnt size, without having lo change the form or pattern 54, we make provision as follows. The bearing 37 and leader or follower 59 are made relatively adjustable,

so as to enable the said bearing to. beshifted' relative to said leader or follower toward or from the axis on which the tool-carrier rocks or swings. In the present instance, the leader or follower 59,-Figs. 15 and 16, Sheet 7, is formed with a slot 591 within which the bearing 37 is fitted, the opposite sides oftho bearing having flattened portions which make sliding contact with the opposite sides of the slot 591. A pin or stud 67 having a scren-'threadc1l'stein is secured to the beari11g' 37 ,'i11](l projects outward. To the said threaded stem is applied the thu1nbnut 69, the latter having a circun'iferential rib 691 engaging with the cap 66 covering the outer end of the slot59l of the leader or follower.

Thumbmut ()9 is free to rotate, but cannot move radially independently of saidcap', and consequently, when said thumb-nut is retated, the bearing is adjusted radially;

i The bearing-38, Figs. 17 and 18, Sheet 5, is made radially adjustable, also, inorder to suit the d'i'lferentsizes of heels upon'which it is desired to work, and also in order to secure the desired inclination of the tool-shaft and tool relative to the axis of the roclishaft' 41.

Thus, the trunnions 70, 70 with which the said bearing is provided at the oppositesides thereof are fitted to bearings which are formed in slides 71, 71 located between the opposite sides of the bearing and the oppo site side-portions of the slotted arm 39,v The said slides have laterally extending projections fitting and working in the radial guideslots 72 in the said sidep(')rtions.

The slides 71, 7.1, are engaged by a crossliead 7,3,in which latter is a hole receiving a thumb-nut 7 4 that is fitted to a screw 75 fixedt'o the inner portion of the arm. 39. The enlarged'or, flanged upper. end of the thumb-nut fits upon the top' of the crosshead, and a ring or washer 7 6 is appliedv to the thumb-nut below the cross-head, Thereby, the thumb-nut is prevented from having movement vertically with relation to the cross-head, while permitted to turn in the hole within which it is fitted. By turning the thumb-nut the cross-head, slides, and bearing, may be adjusted toward or fror'nthe axisof the 'roclrshaft 41 of thetool-carrier, to suit the size of the heels being operated upon,

and to lace the tool-shaft either in arallelism wit "said roclfshaft or at anang e or inchnation with respect to the'rockshaft corresponding with the bevel or inclination whichthe exterior surface of the heel is required to have; that is to say, so that the eX,

terior of the tool will conform n position to the desired shape of theexterior of the heel, and stand atthe angle or inclination which the said exterior is required to have. This capacity for adjustment of the angle-or inclination of the tool-shaf t enables the slope or inclination of the exterior surface of the heel with relation to the top-lift to be varied through a-considerable'range, as required in the case of the heels of footwear for men or women; As the tool-carrying endof the toolshaft swings toward and from the axis of the rocltshaft of thstool-carrier in following around the periphery of the pattern, causing the axis of said tool-shaft to swing toward and from parallelism with the axis oftho rockshalt, the bearing 38 at the inner end. of the.- tool-shaft swivels on' its said pins-or trunnions 70, 70. I

In order to ct'immunicate inovenientof rotation to the tool-shafts, the latter respectively are connected by lengths of flexible shafting, 76 76, Figs; '1, 2'and 4, containing universal joints 77, 77, Figs. 1' and 2 with operating shafts 78, 78, at the'right hand end of the machine in Figs."1 and 2. *As shown in Figs. 1 2, and I), the said operating shafts are furnished with. band-pullers 7 9 79 receiving driving-bands S0 80 which also pass around'band-pulleys 81 81 on the drivingshaft" of the machine l/Vhen the tool-shafts are required to rotate at different rates of speed, the band-pulleys on thesaid driving shaft will vary'in diameter, as shown, and when two or more tool-shafts are re uircd to rotate at the same rate of, speed t 1e same band may be arranged as in Fig. 3 to pass around the band pulleys of the corresponding operating shafts, suitable idler or tension pulleys 82 being provided, as shown.

The bearing 37 is fitted to the tool-shaft in well-known manner so as to prevent endplay of the bearing and tool shaft relative to each other,-and in order tocontrol the. endwise position of the tool-shaft during the radial movement thereof inward and. outward,

so as to cause the toolto followthe line of the heel-seat, the opposite side-portionsof .arm

39 are slotted, as at 58, Fig. 16, Sheet 7, and' within each'slot 58is fittedia slide-bl0ck57l .which is connected with the bearing 37.

Hence/as the bearing moves radially, the said slots 58 control its position. and-that of the tool-shaftendwise so as to cause the tool to act properly with relation to the lineofthe degrees of curvature, the guiding portion of the arm 39 is made adjustable. Herein, the arm is made in two parts, namely, an inner member 401 made U-shaped as shown, and an outer member 402 fitting between the branches or sides of the former and having flanges or ears 64, 64, which project out beyond and overlap the said branches or sides. The two members of the arm are connected together by means of pivots 403, 403, rojecting from the said branches or sides the inner member and fitting holes in the said flanges or ears. This construction of the arm, and mode of connecting the two arts thereof together, enables the slotted guiding portion 402 to be swung on the pivots as required' in order to give any angle to the guides which may be necessary to suit theheel-seats of the particular lot of shoes to be handled.

For the purpose of fixing the parts in position after they have been set or adjusted so as to position the uides properly, each or either of the ears oft e outer part of the arm is formed with a segmental slot 404, Fig. 16,

that is concentric with the pivots 403 403 connecting the two parts. Through the said slot extends the stem of a threaded stud 405 projecting from "the corresponding branch'of the fixed inner part of the arm. By means of a nut 406 and washer 407 applied to the said stud the two parts of the arm are clamped together fixedly.-

.The breasting cutter 90 (see Figs. 1, 2, 19, and 21, Sheets 1, 2, and 10) is attached to a slide or plunger 91 moving in a horizontal line and supported by bearings 92 93 in a. suitable stand 94 that is-attached to the machine-framing. A collar 95 fitted to the said slide or plunger is connected by means of a rod 96 to av crank 97 at one end of a short inclined shaft 98 mounted in a suitable bearing 99' carried by the machine-framing, the other end of the said inclined shaft hav ing affixed thereto a bevel-gear 100 meshing with a like gear 101 on theshaft carrying the cam 49 by which is actuated the rack-bar 46, aforesaid, employed for communicating, .rocking movement to the tool-carriers.

After each movement of the Work-carrier, serving to advance the boots-or shoes tl rreon one stage in the series of finishing tools, and during the dwell thereof in its new position, the tool-carriers are caused to rock so as to carry the respective tools connected therewith around the heels which are in position to be acted upon by the said tools, and at this time also the breasting cutter is caused to act to trim the breast-portion of the heel which is in position to be acted upon by the said breasting cutter. The rocking toolcarriers are operated to carry the corresponding tools from the starting points at the breasts of the heels on one side of the latter, around the backs of the heels, to the breasts at the other sides of the heels, and then 'reversely to the starting point, after whichthe tool-carriers stand at rest. The work-can rier then is advanced another step, and so on alternately. i

We make provision for varying, whenreoperator.

quired, the extent of'the rocking or swinging movement of the tool-carriers, in order that the same may correspond. with the length of heel to be operated upon. The said'movement must be sufficient to carry the tools entirely around the circuit of the heels, but requires to be reduced for small he'els so that the tools will not be carried into the shankportions of the soles too far. The desired result may be attained in different ways within the skill of the mechanic. Herein we have shown provisions for enabling a predetermined amount of lost motion to occur in the action of the devices for transmitting rocking movement to the tool-carriers, and means for adjusting the extent of such lost motion.

Having reference to Fig. 5, Sheet 5, the

' rack 45-is capable of play, lengthwise of rackbar 46, between adjustable collars or nuts- 461, 461, on said rack-bar.

By setting said nuts or collars so as to increase or diminish the amount of lost motion, the extent of the, movement which is transmitted to the toolcarriers will be varied in obvious manner.

For the purpose of rotating the cam 49and drivingbevehgear 101 we employ in connec-, tlOIl therewith a drivmg train embracing start-and-stop devices by-means of which the said driving tram 1s made operative to start the said cam and-bevel-gear and rotate .the same until the required operations of the tools upon the heels in position adjacent the. same have been effectuated, after which the said driving train automatically is disconnected to discontinue'the Working of the cam and driving bevel-gear for the purpose of en- Preferably, the said .start-and-stop devices are of atype enabling the operator to start the rotation of the said cam and driving bevel-gear at will, the said rotation being discontinued automatically at the termination of the required extent thereof.

abling the operator to remove from the Various constructions and arrangements of, driving mechanism containing automatic start-and-stop mechanism suitable for use in the present, connection are known and may be employed, as deemed desirable. By preference we employ a driving train containing a friction-clutch. and in connection therewith a shipper which is automatically controlled and also is under the control of the tages that the members thereof are capable of being separated, if desired, at any instant in the rotation of the cam and driving bevelgear, as for the purpose of obviating accidents or injury to the work, and for the purpose of A-friction-clutch has the advan-x 's ur-gear 108, the said spur-gear having fast 'in dotted lines in Fig. 1.

affording opportunity to inspect the work in process of being finished and also that it enables the cam and driving bevel-gear, together with the parts which are operated from the latter, to be started without shock t ierewith a spur-pinion 109 meshing with'a spur-gear 110 fast on the shaft 50 carrying the said cam 40 and driving bevel-gear 101. For convenience in construction, and to gain compactness, we mount the two clutch-meni bers 102' and 106, and the spur-pinion 107, loosely upon the said shaft. The shipper for the said friction-clutch is constituted by a lever 111 having a fork 112 in engagement with the grooved hub 113 of the loose bandpulley, the said shipper being acted upon by a yielding force, suitably originating and operating with a tendency to separate the clutch members. Herein, we employ a spring 114, Fig. 1, which is shown connected with the machine-framing and also with a lever 115 that is united to the shipper by a connecting-rod 116.

For the purpose of enabling the operatorto move the shipper to close the clutch when it is desired to start the movement of the tool-carriers and breasting-cutter, a treadle 117 is provided, the latter being in operative connection with the said lever 115. For the purpose of holding the clutch closed while the required movements are being communicated to the toolcarriers and breastingcutter, a controlling cam 118 is made fast on the shaft 50, the face of whichcam acts, after the said shaft has begun -to rotate, against a pin or roll 124 carried by an arm 1 19 which is in operative connection with the shipper 111. The said connection .is established in" the present instance by means of a pin 120 projecting from the .arm 119 into a slot 121 (shown in dotted lines in Fig. 1) that is formed in connecting-rod 116'. Normally, the said pin is held locked at one end of the said slot, as by, means of a movable hooked latch 122 which is pivoted to the lever 115 at 221, Fig. 1, and thus the arm 119 and .connecting-rod 116 are locked together so that they are compelled to move in unison. During the rotation of the controlling-cam 118, the face thereof acts against the stud or roll 12 4 of the arm 119 to hold the shipper in position to keep. the clutch in closed and operative position. At the end of the re uired rotation of the cam 49 and driving beve -gear 101 the driving-plower therefor is thrown off automatically, t 's action being governed by the saidcontrolling cam, which latter is formed in-one portion of the circuit thereof with a notch or depression 123. When, in the rotation of thesaid controlling-cam, this notch is presented to the stud or roller 1 24 carried by the arm, the spring 114 is permltted to move the parts with which it is con: nected in adirection to open the frictionclutch and throw 0H the power. Until the said notch ordepression in thecontrolling cam arrives in position to receive the S8Jdstud'or roller, the face of the said acts to hold the shipping-devices in position to maintain the clutch in a closed andoperative condition. a

For the purpose of enabling the frictionclutch to be unship ed at by the op'e'r ator at a moment w en the notch or depress ion of the'controllingcam is notzi'n position to-receive the studo'r roller of the arm afore' I said,;as in case of need or emergency arising while, the tools are working uponthe heels of a set of boots or shoes upon the Work-08,1 rier, the latch 122; is made movable out of engagement with the pin 120 on the said arm, and is provided witha suitable'projec tion 1224 by which it" may be moved for the purpose 'of-effecting the disengagement of thesame from the pin 12 0. When the latch is lifted, the slot in the connecting-rod allows the shipping devices to be moved independently of the said arm 119 by the s ring far enough to open the'clutch The atch may be variously constructed and applied. A-convenient form thereof is shown in Fig.

-1, in which the latch is pivoted to the lever 115 at 221 and has a nose which is beveled off on the under sidethereof to enable said nose to rise up over the pin and r-engage automatically therewith.

The emergency stopping devices are in tended to enable the transmission of movement to the tool-carriers and breasting-cutter to be arrested at will at any instant. The projection 1224 may be taken hold of by and, if desired, for the purpose of disen-- gaging the latch 122, or any'suitable arrangement for enabling the operator conveniently to lift the latch may be employed.- We have shown in Fig. 1 one arrangement,

the same comprising, essentially, an irregu larlyshaped lever 1222, which 1s pivoted to the lever at 221 and provided'with a pedal 1225 The working arm of lever1222 extends beneath projection 1224, in position to engage therewith to lift latch 122 when pedal 1225 is pressed upon.

For the purpose of arresting quickly the rotation-of the shaft 50 afte'rthe'clutch has been unshipped by'the operator in the manner just described, a suitable stop' or brakedevice provided. Thus, .the lever 1222 may be extended and arranged so that when pedal 1225 is pressed upon the free extremity of its working arm Wlll be pressed against the side of the member 106 of thefrictionclutch as will be apparent from Fig. 1.

For the purpose of arresting promptl' the rotation of said shaft 50 after the clutc has been unshipped automatically, as described, a brake-pulley 1061, Fig. 2, Sheet 3 is connected with themember 106 of the frictionclutch, and to the same is applied the brakeband 1062, which is connectedwith brakelever-1063', the latter beingengag e'd by the cam 1064 on shaft 50.

The operation of the work-carrier is effected as follows :For the purpose of relieving the operatorof the strain and fatigue which would be incident to moving the work-carrier manually, as .well as for the further pur pose of leaving him free to attend to other duties, we employpowenactuated operating devices which are contrived and arranged to communicate the necessary. movements to the work-carrier; By means of the said devices the work-carrier is r( tated step-bystep, each advancing movement of partial rotation serving to advance the respective work-supports or picks thereof through a distance corresponr ing with that which separates them from one another. As will be obvious to those skilled in the art, successive advances of the work-carrier will thereby act to occasion relative movement between the work-carrier and tools, to eause'each boot or shoe on the Work-carrier to be subjected to,

the removal of the boot or shoe from the said Work-support or jack is efiected. By placing boots or shoes upon the work-supports or jacks as they come around in succession into position opposite the operator, a constant succession of boots or shoes can be kept passing' through the machine, as will be apparent, and at any given moment a certain number thereof will simultaneously be undergoing 5 'whichis a spur-pinion 153 meshing with .a

'cessive stages of the latter.

See. Figs. 1,2, 7 andS, Sheets 1', 2, 7 and 8. A driving-band 150 extends from a pulley 151 on the driving shaft 1 at the side of the machine, around a somewhat larger pulley 152 on the shaft ,of

spur-gear 154 which ordinarily turns loosely upon the operatingshaft 155 for the workcarrier. The said operating shaft is operatively connected Wit the shaft of the workcarrier for the purpose of communicating movements of partial rotation to the 'workcarrier, as aforesaid, by devices which may vary in practice, crank 156 on the work-carrier operatingshaft, a connecting rod 157 joined with the said crank, a swinging arm or pawl-carrier connected with the said arm or pawl-carrier, and a ratchet wheel 160 which is connected with the shaft 7 of the work carrier. In the carrier operating shaft will advance the work-carrier through one-eighth of a revolution. Any suitable provision may be made for preventing ov'errunning of the work-carrier after each advance thereof. Herein we have shown the shaft 7 "provided with a brake-pulley 161 which is surrounded by a brake-band 162, the latter being operated by meansof a lever 163 and a cam 164 faston the work-carrier operating shaft 155. This cam is set to apply the brake at the end. of each revolution of the said. operating-shaft.

It is necessary prior to each advance of the work-carrier to occasion. a relative movement of the worlecarrier and tools laterally with respect to each other; that is to say, to occasion a relative movement in the direc tion of the length of the shaft of the-workcarrier a suiiicient distance to cause the 'boots or shoes and all portions of the worksupports or jacks carrying the same to entirely clear the tools in advancing, and afterward restore the parts to their normal relative positions, laterally, after the completion of the advance. This relative movement .most conveniently is effected by giving an axial movement to the work-carrier, and in mitting such movement, the shaft of the work-carrier is mounted with capacity to slide lengthwise within its supports. The

fast upon a sleeve 1601, Fig. I, surrounding the shaft 7 of the work-carrier and splined to the latter. The outer ,end of the shaft of the work-carrier has fixed thereon a grooved collar 165 which is engaged by a shifter-fork 1.66 which is operated by the grooved cam 167 on the work-carrier operating shaft.

Preferably, in connection with the powerdriven actuating devices for the work-carrier, we employ manual controlling devices for the purpose of enabling the said actuat ing devices to be caused to act at the will of the operator. Thus, we provide in. the present instance 'start-and-stop mechanism including clutch-devices of the well known per devices co perating therewith. s
